Motion and Forces
Forces
A force is a push or pull
Types of forces
Contact Force
Gravity
Friction
Size and Direction of forces
Balanced and Unbalanced Forces
Forces on moving objects
Newton's First Law relates Force and Motion
Galileo's Thought Experiment
Newton's First Law
States that objects at rest remain at rest, and objects in motion remain in motion with the same velocity, unless acted upon by and unbalanced force.
Intertia
Restistance of an object to a change in the speed or the direction of its motion.
Force and mass determine acceleration
Newton;s second law relates force, mass, and acceleration
Newton's Second Law
States that the acceleration of an object increases with increased force, and decreases with increased mass.
Force Equals Mass Times Acceleration
Force= mass * acceleration------F=ma
Mass and acceleration
Forces can change the direction of motion
Centripetal force
Keeps object moving in a circle
Circular Motion and Newton's second law
Forces act in pairs
Newton's third law relates action and reaction forces.
Action and Reaction Pairs
Action and Reaction Forces Versus Balanced Forces
Balanced Forces
